    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: This exciting and unfamiliar view [7] of the Orion Nebula is a
visualization based on astronomical data [8] and movie rendering techniques.
Up close and personal with a famous stellar nursery normally seen [9] from
1,500 light-years away, the digitally modeled frame transitions from a visible
light representation based on Hubble data on the left to infrared data from
the Spitzer Space Telescope on the right. The perspective at the center looks
along a valley over a light-year wide, in the wall of the region's giant
molecular cloud. Orion's valley ends in a cavity carved by the energetic winds
and radiation of the massive central stars of the Trapezium star cluster [10]
. The single frame is part of a multiwavelength, three-dimensional video that
lets the viewer experience an immersive, three minute flight through the Great
Nebula of Orion [11] .
